@ssimard said in Retina images! Please help!:
Oh and I should also mention that importing through the csv DOES NOT create the 2x retina images, it only works when adding a product via the backend.
So I had to hack the copyImg() function in AdminImportController too...
That interested me for ages!
Great to read about somebody who is interested in best possible image quality in his shop (I know, there is still pagespeed and Google).
I always wondered how to get this done and which is the right workflow to adapt!
Most of the time I am lacking time so I follow the lazy path. I am a Windows user and shoot product images myself. I have them in high res and tried many workflow and still do not know which is best.
Prestashop as TB have their own way of shrinking images. For a year or so I also installed M. Dekkers :) ImageMagick module that trims also white space.
But I thought that programs that are specialized on shrinking images, even lossless, that exists for years now can do the job better. Moreover, they are easier to use on a bunch of images via batch that the backoffice uploading of images or CSV import way of Prestashop.
To name are PNGout, PngOptimizer (Freeware) and the Riot plugin. These offer a nice user experience since they work well with XNview, IrfanView, standalone and others lXN forum .
So, I shrinked all my digital product images and even those images of my template in batch via those tools.
Nowadays, eventually, there is a very cool tool for windows users that runs images in batch against dozens of those optimizuers for free by Javier Gutiérrez Chamorro (Guti): FileOptimizer
In a nutshellm, I wonder if that was not contra productive or in contrast to the main aim ti improve image quality in the shop while at the same time reducing loading time since Prestashop applies its own shrinking magic?!
PS:
I set Prestashops's image option in BO to 100% or 90% in order to minimize the shrinking, so called optimizing, of already shrinked images.
What do you think about this worklow?
Makes it sense to compress images before we load/import them into TB/Presta? As you know there are some modules/services on the market that state the same but take money and bandwith for this purpose.
